Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139252, here are decompositions:
- 11 + 139241 = 139252
- 53 + 139199 = 139252
- 83 + 139169 = 139252
- 131 + 139121 = 139252
- 173 + 139079 = 139252
- 293 + 138959 = 139252
- 353 + 138899 = 139252
- 359 + 138893 = 139252
Showing the first eight; more decompositions exist.
